Displaying image from a file using ImageIcon in Java

Java

Hi all of you!

I wanna create a JFrame, on which I must display an image from a file on my computer (Actually I'm going to create a Captcha image). Under this picture I must show a JTextField (so that after, let's say, seeing the picture above, I can enter the string).

I've tried like this:

package drawingUsingImageIcon;

import java.awt.FlowLayout;
import javax.swing.*;

public class ImageIconDemo extends JFrame{
	private ImageIcon icon;
	public ImageIconDemo()
	{
		super("Image Icon Demo");
		setVisible(true);
		setSize(330, 260);
		JLabel	label = new JLabel();
				
		setLayout(new FlowLayout(FlowLayout.CENTER));
		
		label.setSize(270, 200);
		add(label);
		setPicture(label, "bruce-lee2.jpg");
		
		JTextField textField = new JTextField(20);
		textField.setVisible(true);
		add(textField);
	}
	private void setPicture(JLabel label, String fileName)
	{
		icon = new ImageIcon(fileName);
		label.setIcon(icon);
	}
	public static void main(String[] args)
	{	
		ImageIconDemo frame = new ImageIconDemo();
	}
}

What I've got is that a window with my picture "bruce-lee2.jpg". But the textField haven't appeared. But after I've minimized the window, I've got the textField as I expected. That sounds very strange to me.

So could any body tell me what is the reason in this case?

Longing for the replies!

Thank you in advanced!
